I haven't had a chance to get it in the air yet, but I'm having an issue with the rear driveline/suspension. 
Where I accelerate moderately, upon let off I can feel a shift in the right rear wheel.  Almost like it's loading up and then returning to position when I let off.  Substantial feel, most notable at 30ish mph. 
100k on the car. Pedders springs and fe3 shock/struts installed at 60k.  I'm due for shocks/struts, but this doesn't feel like a shock issue, unless it's loose.
